Looking for a compact, all-in-one solution to safely charge and protect your 18650 lithium batteries? This 1-20PCS 1A 18650 Lithium Battery Protection Board integrates TP4056 charging technology with overcharge, over-discharge, and short-circuit protection — all in a single plate module. Whether you’re building DIY power banks, flashlights, or portable electronics, this module delivers safety and convenience in one tiny package.\n
Key Features You’ll Love
✅ Triple Interface Support: Compatible with Type-C, Micro USB, and Mini USB — charge your batteries using any common cable.
✅ Built-in Protection: Includes over-voltage, under-voltage, over-current, and short-circuit protection for enhanced battery longevity and safety.
✅ TP4056 Charging IC: Ensures stable 1A constant current/constant voltage charging for optimal battery health.
✅ One-Plate Design: All components integrated onto a single PCB — easy to install, minimal wiring, and space-saving.
✅ Versatile Use: Ideal for DIY projects, power banks, solar chargers, LED lights, and more.
Why This Module Stands Out
Unlike basic charging boards that lack protection, this module actively safeguards your batteries against common failure modes. The inclusion of Type-C alongside legacy Micro and Mini USB makes it future-ready while maintaining backward compatibility — perfect for users with mixed cable inventories.
At just $6.67, this is an unbeatable value for a protected charging solution. Whether you’re buying one for a single project or stocking up (up to 20PCS available), you’re getting professional-grade battery safety at a fraction of the cost of premium alternatives.
